6 Claims. (Cl. 98--88) The present invention relates to improvements inwindow constructions and the primary object of the invention is toprovide a window sash having a fixed upper glazed portion and a movablelower shield portion forming a closure for the lower portion of the sashand capable of being disposed in various adjusted open positions withrespect to the upper fixed portion for ventilatin purposes, the entiresash structure capable of being readily mounted in a window frame ofsimple and inexpensive construction.

A further object of the invention is to provide a window which is devoidof sash cords and weights, and one wherein ventilation may be obtainedwithout objectionable drafts entering the room.

A further object resides in the novel arrangement whereby the rockableand slidable ventilating shield will provide a weather tightconstruction when in closed relation in the sash.

A still further object resides in the novel means for screening thelower portion of the sash against entrance of insects when the shield isopen, and permitting ready cleaning of the upper fixed glazed'portion ofthe sash.

A still further object is to provide a window sash of this characterhaving an open lower portion closed by a rockable and removable shieldportion which is also capable of being slid into overlying relation tothe fixed upper portion of the sash.

Other objects and advantages of the invention will appear in thefollowing detailed description, taken in connection with theaccompanying drawings, forming a part of this specification, and inwhich drawings Figure 1 is a plan View looking at the inner side of theimproved window sash with the ventilating shield in a closed position inthe lower portion of the sash.

In the drawings and wherein like reference characters designatecorresponding parts thruout the views, the letter A may generallydesignate the improved window sash and B a. window frame or other casingin which the sash is mounted.

The frame or casing B may be suitably mounted in a window or other wallopening C and comprises a plain rectangular frame or casing of wood orother construction in which the sash A is mounted in any preferredmanner.

The sash A comprises parallel side rail 6, a bottom rail 7 and a toprail 8. Connecting the side rails 6 substantially midway of their heightis a medial or parting rail 9 dividing the sash into upper and lowerportions I9 and H respectively. The upper portion l6 may be termed thefixed or closed portion of the sash and is suitably glazed with glass asat l2, while the lower portion ll of the sash, below the parting rail 9may be termed the open portion of the sash and this lower portion of thesash is provided with a rockable and slidable ventilating shield l4. anda screen member I5.

Referrin now to the construction and arrangement of the closure formingventilating shield It, the same comprises a glass deflecting shield Itprovided along its side edges with metal channel members ll whichembrace the ends of the shield and have triangular end flange portions18 and I9 embracing the cut away corner portions of the glass shield.Extending inwardly in line with the web of each channel member I! is alockin tongue or rib 2B which extends thruout the length of the channel.Associated with each end of the shield It is an end shield or wing 21 ofsegmental shape having an arcuate upper edge provided with notches 22,and provided along its outer edge with a right angular stop flange 23.These end shields 2|, as shown in Figures 5, '7 and 8, overlie theconfronting faces of the side rails 6 between the bottom rail 1 andparting J rail 9 of the sash. As shown also in Figures 7 and 8, the siderails 6 are rabbeted as at 24 to receive the stop flange 23 and limitinward rocking of the shield I l.

Secured along the inner edge of each end shield or wing 2| is a channelmember 25 including a U- shaped portion which embraces the edge of thewing, and these channel members may be secured to the Wings by strikinglugs from the flanges of the U-shaped portion into the wing as at 26 inFigure 12.

Extending inwardly from the inner side of each channel member 25 areflanges 21 and 28 which form guides for the ends of the shield M toslide in. The flange 28 along the inner edge of the wing 2| is ofL-shape and has its free edge directed toward the flange 21 to form aslot for receiving the tongue 20. Extending from the outer side of eachchannel member 25 is an L- shaped flange 29 forming a slot into whichthe inner edge of a facing plate 39 extends when the shield is closed asin Figures 7 and 8. These facing plates 3|] extend along the confrontingfaces of the side rails 6 between the bottom rail 1 and parting rail 9.The side rails 6 are rabbeted as at 3! to form a slot into which theflange 29 extends when the shield is closed, This interfitting of theplate 321 and flange 29 renders the assembly draft proof when the shieldis closed.

Secured to the bottom rail 7 with its ends extending into the lower endsof the rabbets 3| is a trough 32 in which the ventilating shield i4 isrockably supported. This trough 32 may be formed from sheet metal andincludes a bottom wall33, a vertical wall 34 along the outer edge of thebottom wall, and a divergent wall 35 along the inner edge of 'the bottomwall. The wall 34 terminates short of the ends of the trough toaccommodate the end shields 2| and flanges 2], while the wall 35 extendsinto the rabbets 3|. The ends of the trough are closed by end walls 35.A strip of rubber or other yieldable material 3'! may be disposed in thebottom of the trough for the glass shield I6 to rest upon and form aweather tight arrangement.

Recessed into the inner face of the parting rail 9 is a rubber or feltcushioning and sealing strip 38 against which theshield l abuts when ina closed position. Thus, when the shield I6 is closed, the same issealed at its upper and lower ends by the strips 38 and 31 respectively,and along each side edge by the interfitting'of the plate 3|! and flange29. Secured to the under side of the parting rail 9, adjacent each endof the rail, is a keeper 39 each having a spring urged ball normallyurged against its adjacent end wing 2! and adapted to engage in thenotches 22 for retaining the ventilating shield in various adjustedpositions. A handle all is secured to the upper flange portion I8 ofeach channel member H by means of a screw or the like 4|, and thesescrews also serve to clamp the members I! to the glass shield. Thesehandles ll] serve as pulls for rocking the shield.

Secured to the lower flange portion l9 ofeach channel member I! is alift handle 42. These handles 42 are secured by screws 43 which alsoserve'to clamp the members I to the glass shield. The cut-away cornerportions I6, shown in Figure l, at the lower edge of the shield l6,together with the flange portions l9, provide chambers for receivingsliding lock bolts 44 normally urged toward the ends of the shield bysprings 45 enclosed in the handles 42. These bolts M extend thruopenings in their respective channel members l1, and when the shield I4is in a closed position, have their ends projected thru the end shields2i and into openings 46 in the side rails 6. Thus the bolts d4 serve tolock the shield I4 against sliding and rocking movement. Suitablehandles 4'! serve for operating the bolts 44.

Secured in each of the inner rabbets 3| of the side rails 6 in alignmentabove each of the channel members is a guide channel 59. These guidechannels are open at their confronting sides and are adapted to slidablyreceive the channel members H of the deflecting shield I6 when theshield is raised in the sash as in Figure 3, into overlying relation tothe glazed upper portion of the sash. These guide channels are formedwith grooves 5! in which the ribs 20 slide and prevent lateral shiftingof the shield, as shown in Figure 9. When the shield is in a raisedposition, the bolts 44 are projected into openings 53 in the side railsB for retaining the shield raised.

Thus the ventilating shield |4 may be rocked in the trough 82 forcontrolling the air entering thru the lower open portion of the sash,and the deflecting shield l6 may be slid upwardly in the sash to providea fully open lower sash portion. It will be observed that the shield IEslides in the end wings 2| upwardly into the guide channels 50.

Referring now to the screen member [5, the same is mounted in the loweropen portion H of the sash between the end wings 2| of the ventilatorshield so as to swing outwardly of the sash. The screen member |5comprises a frame 55 fitting in the outer side of the sash A anddisposed entirely within the plane ofthe sash, as shown in Figure 5. Theupper rail of the frame 55 fits in a rabbet formed in the under side ofthe parting rail 9, while the lower rail of this frame fits in a'rabbetformed in the upper side of the bottom rail 1 of the sash. One side railof the screen frame carries hinge eyes 56 at the outer side of the railfor receiving hinge pins 51 provided'on hinge plates 58 secured to thesash rails and 9. The top and bottom rails of the screen frame, adjacentto the opposite side rail, are provided with spring latches 59 havinglatch bolts adapted to be projected into latch openings 60 provided inthe sash rails and 9 for retaining the screen memher in a closedposition in the sash opening. A

suitable screening 6| such as screen wire or the like, is securedover'the outer side of the frame 55 as by a; wire retainer 62. a

The screen member I5 is also adapted to serve as a storm sash whendesired by the insertionof a pane of glass 63 into the frame. Theframe55 is provided'at the inside of its marginal rails with an inwardlyopening channel 64 in which-is disposed a sealing strip 65, such as ofrubber, felt or the like, and against which the glass 63 seats and isremovably retained as by means of suitable retaining means 66. a Asshown in Figures '7 and 8, the screen memher is is disposed between theend shields 2| so that these shields may pass between the ends of thescreen member and the side rails of the sash frame upon rocking of theventilating shield, As shown in Figure 6, the end shields 2| are of suchwidth at their lower portions as to extend between the ends of thescreen and sash side rails and thus close the space between the ends ofthe screen and the sash side rails.

Thus when the ventilating shield I4 is in a lowered position, as inFigures 1 and 2, the shield may be rocked to provide various degrees ofventilation, and when the deflecting shield I6 is in a raised positionas in Figure 3, full ventilation may be had thru the lower portion l lof the sash. Also, when the shield I6 is raised, in the screen member l5may be swung out to permit ready cleaning of the outside of the upperglazed portion It of the sash.

While the channel members 25 have been shown as metal members secured tothe inner edges of the end wings 2!, which are preferably formed of asuitable plastic material, these channel members 25 may also be formedof a plastic material and made as an integral part of the end wings.Likewise, various other portions of the structure may also be formed ofplastic materials whenever such is found practical and desirable.
